Description
Gewinnung von Metallen aus Lösungen. Es ist bekannt, daß sich Zellulose und zelluloseähnliche Substanzen zur Absorption von Schwermetallsalzen aus Lösungen eignen (Patent 18q.150_ und französisches Patent 38341a). Die von Rohzellulose festgehaltenen :Metallmengen sind aber, wie wir festgestellt haben, recht gering. Z. B. absorbieren Rohbaumwolle oder Holzsägespäne nur bis ein Zweihundertstel ihres Gewichtes an Kupfer aus einer verdünnten klaren, ammoniakalischen Kupferlösung.Extraction of metals from solutions. It is known that cellulose and cellulosic substances for absorbing heavy metal salts from solutions suitable (patent 18q.150_ and French patent 38341a). Those held by raw cellulose : However, as we have found out, the amount of metal is quite small. E.g. absorb Raw cotton or wood sawdust only up to a two-hundredth of its weight in copper from a dilute, clear, ammoniacal copper solution.
Eingehende Untersuchungen haben jedoch die überraschende Tatsache ergeben daß der Zellulose eine ganz bedeutend verstärkte Absorptionsfähigkeit verliehen werden kann, wenn man sie durch physikalische oder cheinische Behandlung auflockert.In-depth research, however, has the surprising fact show that the cellulose is given a very significantly increased absorbency can become if one loosens them up through physical or cheinical treatment.
Zunächst hat sich gezeigt, daß z. B. Rohbaumwolle oder Holzsägespäne durch Behandlung mit Harz, Fett oder 0I lösenden Stoffen eine Absorptionsfähigkeit erlangt, welche drei- bis fünfmal höher ist als bei unbehandelter Zellulose.First, it has been shown that, for. B. Raw cotton or wood sawdust by treatment with resin, fat or oil-dissolving substances an absorption capacity obtained, which is three to five times higher than with untreated cellulose.
Beispiele: Aus einer verdünnten ammoniakalischen Kupferlösung absorbierten: i. io kg nicht vorbehandelte Kiefernholzsägespäne 40 bis 5o g Kupfer, dagegen nach Iaitferziung der Harz- und Ölbestandteile niit Äther oder Benzin io kg Kiefernli,Dlzsägespäne Zoo bis 25o g Kupfer, 2. i o kg nicht vorbehandelte Baumwolle 30 bis 40 g Kupfer, dagegen nach Entfernung der Harze und Fette mit Äther io kg Baumwolle 12o bis 150 g Kupfer.Examples: From a dilute ammoniacal copper solution: i. 10 kg of untreated pine sawdust 40 to 50 g of copper, on the other hand, after the resin and oil constituents have been extracted with ether or petrol, 10 kg of pine, wood sawdust up to 25o g of copper, 2 10 kg of untreated cotton 30 to 40 g of copper, on the other hand after removal of resins and fats with ether 10 kg of cotton 12o to 150 g of copper.
Weiterhin hat sich gezeigt, daß durch Behandlung mit Dampf ebenfalls eine erhöhte Absorptionswirkung erzielt wird, wenn die Einwirkung des Dampfes so kräftig und anhaltend ist, daß das Harz dadurch entfernt wird.Furthermore, it has been shown that treatment with steam also an increased absorption effect is achieved if the action of the steam so strong and persistent in that it removes the resin.
Beispiele: Es absorbierten aus einer verdünnten aminoniakalischen Kupferlösung i. io kg Kiefernholzsägespäne nach der Behandlung mit Wasserdampf ioo bis 12o g Kupfer, 2. io kg Baumwolle nach der Behandlung mit Wasserdampf 8o bis ioo g Kupfer.Examples: It absorbed from a dilute aminoniakalischen Copper solution i. 10 kg of pine sawdust after treatment with steam 100 up to 12o g copper, 2,10 kg cotton after treatment with steam 80 to 100 g of copper.
In gleicher Weise wie physikalische Hilfsmittel wirken gemäß zahlreicher Versuche chemische Mittel, und zwar stets dann, wenn dadurch eine Auflockerung des Absorptionskörpers erzielt wird. Die für diesen Zweck in Betracht kommenden Verfahren sind naturgemäß zahlreiche. Sehr günstige Erfolge wurden erzielt durch Behandlung mit Alkali und Chlorlaugen, Zinkchlorid und Kalziumchloridlösungen sowie verdünnten Säuren.In the same way as physical aids work more numerous Try chemical agents, always when they loosen up the Absorbent body is achieved. The procedures to be considered for this purpose are naturally numerous. Very beneficial results have been achieved through treatment with alkali and chlorine solutions, zinc chloride and calcium chloride solutions as well as diluted Acids.
Die Wirkung dieser Stoffe auf Holzsägespäne oder Baumwolle beruht bekanntlich auf einer starken Aufquellung un<1 somit )l:erflächenv ergrößerung.The effect of these substances is based on wood sawdust or cotton known to be due to a strong swelling un <1 thus) oil surface enlargement.
Beispiele: io kg Lärchenholzsägespäne wurden in der Wärme der Einwirkung von 2o 1 konzentriertem Chlorwasser während _# bis io Minuten ausgesetzt. Nach Entfernung des Chlorwassers durch Auswaschen mit Wasser konnten damit etwa 220 g Kupfer aus einer verdünnten klaren und ammoniakalischeii Kupferlösung herausgeholt werden.Examples: 10 kg of larch wood shavings were exposed to the action of 2o 1 concentrated chlorinated water for _ # to 10 minutes in the heat. After removing the chlorine water by washing it out with water, about 220 g of copper could be extracted from a dilute, clear and ammoniacal copper solution.
Das auf den Sägespänen niedergeschlagene Kupfer konnte durch Herauslösen mit verdünnter Säure restlos in Form einer kupferreichen Lösung gewonnen werden. Die Sägespäne waren für erneute Absorption i n gleicher Weise befähigt. Die Operation kann endlos wiederholt werden. Die Anwendung der Sägespäne bedeutet außerdem den erheblichen Vorteil, daß sie gleichzeitig als sehr wirksames Filter dienen, die Filtrate sind vollkommen farblos, und die Filtrationsgeschwindigkeit ist eine sehr große.The copper precipitated on the sawdust could be removed by removing it can be obtained completely in the form of a copper-rich solution with dilute acid. The sawdust was able to be reabsorbed in the same way. The operation can be repeated endlessly. The use of sawdust also means that considerable advantage that they also serve as a very effective filter that Filtrates are completely colorless and the rate of filtration is very high size.
Das `erfahren eignet sich auch für solche Fälle, -%vo es nicht darauf .ankommt, die Metalle wieder zu gewinnen, sondern Abwässer von schädlichen Bestandteilen, z. B. Eisen oder Mangan, zu befreien. Auf diese Weise ist es möglich, durch Filtration von eisenhaltigen Gebrauchswässern über vorbereitete Holzsägespäne das Eisen restlos zu absorbieren. Es wird als bekannt vorausgesetzt, Torf-=null u. dgl. zur Verwendung als Klärmittel durch Kochen oder Dämpfen geeignet zu .nachen.The experience is also suitable for such cases, -% of it is not on it . arrives to recover the metals, but waste water from harmful components, z. B. iron or manganese to free. In this way it is possible through filtration from iron-containing industrial water to prepared wood sawdust, the iron is completely removed to absorb. It is assumed that peat = zero and the like are known to be used suitable as a clarifying agent by boiling or steaming.
